A series of novel, highly potent, and orally bioavailable next-generation tricyclic peptide PCSK9 inhibitors

…, D Branca, T Bueters, N Buist, SN Ha… - Journal of Medicinal …, 2021 - ACS Publications
… We believed that the N-methylation was changing the conformation to twist the peptide
backbone, thereby slightly weakening the key H-bonding interactions (13) with the PCSK9 β-…

A novel selective allosteric modulator potentiates the activity of native metabotropic glutamate receptor subtype 5 in rat forebrain

…, W Lemaire, M Wittmann, MA Jacobson, SN Ha… - … of Pharmacology and …, 2004 - ASPET
We found that N-{4-chloro-2-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}-2-hydroxybenzamide

Orally bioavailable macrocyclic peptide that inhibits binding of PCSK9 to the low density lipoprotein receptor

…, RM Garbaccio, ED Guetschow, Y Guo, SN Ha… - Circulation, 2023 - Am Heart Assoc
Background: Inhibition of PCSK9 (proprotein convertase subtilisin/kexin type 9)-low density
lipoprotein receptor interaction with injectable monoclonal antibodies or small interfering …

Molecular simulations identify binding poses and approximate affinities of stapled α-helical peptides to MDM2 and MDMX

JA Morrone, A Perez, Q Deng, SN Ha… - Journal of chemical …, 2017 - ACS Publications
Traditionally, computing the binding affinities of proteins to even relatively small and rigid
ligands by free-energy methods has been challenging due to large computational costs and …
